Hey ---Many circuit simulators have free evaluation versions with greatly reduced capability. They are good enough for a lot of everyday circuits (if you are not trying to design a reverse-frabulated thurblig, for example). The one I use is MicroCap from Spectrum Software, which is excellent. The drawing interface is excellent, and you can draw things just as a sketch that the analyzer won't operate on. Go to http://www.spectrum-soft.com/index.shtm and click on "Download the free evaluation version" from the red window. It's very easy to learn and very intuitive. I was surprised that it would even analyze a circuit from 1891, but it's up to the task.

Yes, the circuit with the spark gap in parallel with the transformer secondary is the preferred configuration. Both will work with comparably, but having the spark gap in parallel with the transformed protects the transformer from the RF while the gap is conducting. There are surely better things but I've just used Microsoft Paint. Once you figure out how to copy & paste, you can cobble together a circuit. Yes the NST case and secondary base should go to an independant RF ground.

I see lots of different opinions on how the spark gap and the capacitor bank should be placed. This one: https://commons.wikimedia.org/wiki/File:Tesla_coil_3.svg and this one: https://commons.wikimedia.org/wiki/File:Tesla_coil_4.svg My intuition says that the safest one is the first option, but I am interested in what you think. Also does anyone know a good (free) program to draw electrical diagrams? I will have to make a detailed diagram including the MMC (with bleeders). I also have some doubts as to how grounding works. Do you ground the NST and the secondary coil on the same connection? Or is it done seperately? (So I have decided some parameters with JAVATC. I will probably send the results later since I don't know if everything is done correctly.)
